Amenorree Flashcards
definition
For amenorrhea Refers to the lack of menstrual flow in the period of sexual maturity. So, between
menarche and menopause, excluding the amenorrhea of pregnancy and That by breastfeeding (amenorrhea
physiological), every other amenorrhea is to be Considered patologic.
Moreover, we Distinguish primary amenorrhea, a when at the age of 18 years have not yet Appeared flows
menstrual, and secondary amenorrhea, a when you have amenorrhea for at least 3 months after a period of
regular menstruation.
classification
primary amenorrhea, a when at the age of 18 years have not yet Appeared flows menstrual
secondary amenorrhea, a when you have amenorrhea for at least 3 months after a period of
regular menstruation.
Amenorea could be because of:
- anatomical and functional abnormalities of the uterus and / or lower genital tract: amenorrhea uterine and vaginal
- Alterations anatomical and functional borne ovary: ovarian amenorrhea
- Alterations anatomical and functional adenohypophysis and / or hypothalamus: hypothalamic amenorrhea pituitary
- incoordination of the hypothalamic-pituitary-ovarian: amenorrhea alterations mechanisms feedback
- extragenital disorders: endocrine Extragenital, general diseases, metabolic disorders
Amenorrhea source uterine and vaginal. Causes.
Between changes in the uterus and lower genital tract That determinates primary amenorrhea, there are the
congenital malformations,: such as partial or complete agenesis of the vagina, uterine agenesis, cervical atresia,
cable uterine atresia
Also:
- Rokitansky-Kuster-Hauser syndrome
- uterine synechiae intracavitary
what is Rokitansky-Kuster-Hauser syndrome
Rokitansky-Kuster-Hauser syndrome
caratterizzata by aplasia vagunale and uterine horns atretic. The
ovary, However, are normal with normal development of secondary sexual characteristics. This syndrome,
then, is associated with other malformations of the urinary tract
what is sinechie uterine intracavitarie?
can be traumatic and post-emergence after revisions
partum or after incomplete abortions (Asherman’s syndrome) or arise from infection
endometrial (TBC, Chlamydia, sepsis IUD), or even as a result of intervention on the cervix or in
Diatermo-coagulation. The uterine synechiae That determinates complete obliteration of the cavity or
occlusion of the cervical canal, induces secondary amenorrhea, Unless they start earlier
puberty (tuberculous endometritis), causing primary amenorrhea
what is criptomenorrhea?
In the presence of obstruction of lower genital tract are talking about criptomenorrea; in cases of imperforate hymen the
menstrual blood can not drain out and collects first in the vagina (ematocolpo) and
later in the uterine cavity (ematometra) with onset of menstrual pain recurring
Amenorrhea of ovarian origin
Gonadal dysgenesis (primary Am hypergonadotropin with low estrogen level)
Polycystic ovary syndrome
Early menopause
resistant ovary syndrome
ovarian tumors
Gonadial dysgenesis
Gonadal dysgenesis (primary Am hypergonadotropin with low estrogen level)
- dysgeneses in undifferentiated gonad (Turner syndrome and its variants: Lack of ovaries(streak gonads; Female phenotyps; Sexual infantilism
- differentiated donadal dysgenesis: the damage it causes less severe That. hypoplasia ovarian follicular heritage scarsp
- syndromes with sexual ambiguity: These include the real and ermafroditismi pseudoermafroditismi male and female.
syndromes with sexual ambiquity
syndromes with sexual ambiguity: These include the real and ermafroditismi pseudoermafroditismi male and female. Are ailments linked to abnormalities
Chromosomal with discordance between phenotype and genetic sex and / or gonadal you
accompanied by primary amenorrhea. Among the bad pseudoermafroditismi deserves
mention testicular feminization syndrome or syndrome Morris, caratterizzata
by female phenotype with gonads and the hormonal Typically bad
Polycystic ovary syndrome (etiopatogeneze, clinic, diagnostic)
- Aetiopathogenesis unknown
- Clinic
- Mostly secondary amenorrhea
- Anovulatory infertility
- Hirsutism and acne ipeandrogenismo
- Metabolic syndrome
- ultrasound Appearance: ovaries appear increased volume, and with whitish albuginea thick
Polycystic ovary syndrome (hormonal framework)
hormonal Framework
LH increased
FSH normal or low
Reversal of the relationship FSH / LH
Hypersecretion of androgens by the theca cells and stromal ovarian
Increased estrogen, Also Of Those peripheral, produced by adipose tissue and
adrenal gland,: such as estrone: These abnormally high levels of estrogens, Altering
That feedback mechanisms regulate the Increase cyclic gonadotropin,
would be responsible dell’anovulazione with amenorrhea and infertility
Early menopasue (etiopatogeneze)
Aetiopathogenesis is unknown. We hypothesized That a genetic disorder results in hypoplasia
ovarian follicular patrimony reduced. Other times, However, the normal ovaries appear
morphologically and Contain a normal number of follicles That, for different Reasons
(Viral agents, radiation, autoimmune phenomena) would face rapid and premature
destruction
early menopause (clinic)
In severe cases: primary amenorrhea with hypergonadotropic ipoestrogenica
non-appearance of secondary sexual characteristics
In other cases: Develops before un’oligomenorrea with anovulatory cycles and, then,
secondary amenorrhea ipergonadotropica ipoestrogenica, with the appearance of
estrogen deficiency symptoms typical of climacteric internships
what is resistant ovary syndrome?
resistant ovary syndrome: is caratterizzata receptor ovarian insensitivity to pituitary gonadotropins, possibly two to congenital deficiency receptor, by the presence of antibodies antirecettori ovarian or chromosomal abnormalities. Manifests, in general, with amenorrhea primary in young donni with pubertal development and normal secondary sexual characteristics
endocrine framework in resistant ovary syndrome; biopsy
The framework endocrine shows characteristically high levels of gonadotropins and hypoestrogenism: also,
Given the resistance ovarian, administration of gonadotropins is not accompanied by
improvement of the clinical picture.
Biopsy, the number of primordial follicles is normal.
ovarian tumors
give secondary amenorrhea iperestrogenica, sometimes alternating with menorrhagia. It can
be linked to the presence of functioning tumors of the ovary, Which produces estrogen,: such as tumors
granulosa cell and tecomi. Alternatively, it may be linked to the presence of tumors, as
the arrenoblastoma, That produces androgens: In These cases, in Additions to the menstrual disorders, It has
virilization with appearance of male sexual characteristics
hypothalamic - pituitary amenorrhea
- functional hypothalamic amenorrhea associated with disorders
- amenorrhea related to organic lesions hypothalamic-pituitary
- Pituitary adenomas prolattinosecernenti
- iatrogenic causes
- syndromes associated with galactorrhea
- Sheehan syndrome
- empty saddle(balnas) syndrome
functional hypothalamic amenorrhea associated with disorders
- psychogenic amenorrhea
- psychogenic Anorexia
- Pseudociesi or imaginary pregnancy
- post-pill amenorrhea without galactorrhoea
psychogenical amenorrhea
Secondary amenorrhea Arising are, in general, in youth
women undergoing psychological pressure of various kinds (fear, stress tests, or
sports competitions, crash dieting). Are reversible, usually you, the cessation of the stimulus
stressor. Are anche related to insufficient release of hypothalamic GnRH for
central inhibition and are caratterizzata by:
Gonadotropins very low
Estrogen below normal
Anovulation
